Board doesn't have integrated graphics as such but your i5 4590 should have.
If this is an ongoing issue you'd be better physically removing the 290x from the system and then trying the motherboard video output.
A 290x is the most likely thing to have crapped out there and if it has and its still fitted it may be the reason the onboard video output is still disabled.
I am pretty good with hardware, understanding and finding what went bad , but this thing... just when I think I have something to go off of, it changes.
And that's why I wanted to rule out the mobo immediately. Because I know the PSU is good.
Example- when I replaced the psu and ran it bare bones, it would continually run.
So, then I hooked everything up, and everything ran but wouldnt put any video up (that means not posting right?)
By run, I mean all the fans worked, case, videocard fan, chip fan.
I went back to taking stuff out and even bare bones it starts and restarts every 30 seconds. so, that changed. The only thing I can figure is that somewhere along the lines there is a short. /shrug I dont even know. Wish I had some real tools and a bench.
With the 290x removed, the onboard video still doesn't work.
I messed with the monitor while it was coming up--and something came through UEFI Bios (briefly) then it started the restart chain again.
I was trying to save myself time and
at the very least rule out the mobo before I start taking everything apart.
Some of these things, I just don't know.
-if my fans all work, and that shows that the mobo is getting power---could the mobo still be messed up?
-I asked about the lights so I could rule out the mobo. Is there even a way to find out if the
-Should the Mobo be able to start without any ram at all?
